bool UnmapOnlyEnlargeOnOom ()x86 may generate duplicate TLB entries if changing the translation size of mapping, but this
does not lead to any incorrectness as long as the we invalidate the TLB (which we do),
therefore unmap is safe to split large pages without enlarging.

zx_status_t MarkAccessed (vaddr_t vaddr, size_t count)On x86 the hardware can always set the accessed bit so we do not need to support the software
fault method.

cpu_mask_t active_cpus ()Note: these load/fetch_or calls use the seq_cst memory ordering. Although some of the call
sites of these methods *may* be able to tolerate more relaxed orderings, most of them require
strong orderings and this should not be changed.
